After installing the latest Addon Manager update today I now find, using the FSLabs A319 on GPU, that a Refuelling Request via the GSX Menu shuts down the entire power system on the aircraft. I've reloaded and tried this twice. Same both times. I've never had this before and have used this automatic feature at least 50 times. I'm at Stand 33 LSGG.
It seems specific to LSGG as I'm now at LIMC and everything is working normally.
Maybe I've worked this out now. LSGG has been updated to SODE jetways. Does the jetway need to be connected to the aircraft before refuelling? The FSLabs A319 loads up ready connected to the GPU so this seems strange to disconnect prior to moving the jetway onto the aircraft?
